Final answer:
The properties of a time signal include the time interval, frequency, amplitude, and phase.
Step-by-step explanation:
Properties of a time signal can include the time interval, frequency, amplitude, and phase. The time interval is the duration between two events, which can be measured in seconds. Frequency refers to the number of cycles or oscillations per second and is measured in hertz. Amplitude is the maximum displacement of the signal from its equilibrium position, and phase refers to the position of the signal within a cycle.
